Once again, it seems deceptive to me to compare the C's in this...well, maybe Cincinnati and Cleveland, since they have similar areas, but Columbus has annexed so much of what would be suburban-type areas in Cleveland, that definitely impacts their numbers. For example, Parma is considered separately from Cleveland here - now, correct me if I'm wrong, but my impression is that the Parma-equivalents in Columbus would be part of Columbus...so if you add Parma's numbers into Cleveland's, that drops it to 1 in 53.
Now, how many other Parma-like areas would be added to Cleveland's numbers if it were 210 square miles rather than 77 or 78? No idea...but I don't know that these figures really speak to the likelyhood of you getting your car stolen in either city.
